no network adaptors available in device manager

having just changed my operating system from Win98 to XP, my broadband connection is not available. I can see the icon in network connections but its saying 'unavailable - device missing'. What should I do?
Thanks

 

Update the drivers for the device
Look in COntrol Panel SYstem Hardware Device Manager and see if there are any problems like a yellow !

 

Hi there, thanks for your reply but the only yellows visible are related to multimedia contoller and multimedia video controller. Any other ideas?

 

Update the drivers for the network adapter.

Does it show a Network adapter in device manager

 

no, thats the problem. there's nothing displayed.

 

Is the network interface on the mother board or is it on a card. IF the later, re-seat it.

 

sorry I dont understand what this means?
